This paper proposes a two-stage method integrating visual foundation models (VFM) and diffusion models. The segment anything model (SAM) as VFM is combined with the SegRefiner diffusion model to construct the SAM-SegRefiner framework for automated segmentation of edema, inflammation, and thrombus regions in histopathological images of hemorrhoidal tissue, providing a reproducible technical tool for the objective quantification of pathological morphology and its application in traditional Chinese medicine (TCM) syndrome research. Trained and validated on multi-center retrospective data, the SAM-SegRefiner model achieved an average pixel accuracy of 95.32% and a mean intersection over union (mIoU) of 66.81% on an independent test set, significantly outperfor-ming comparative models such as U-Net, MixU-Net, and SAM-Med2D, and also demonstrating robust cross-center generalization capability. Furthermore, by correlating the quantitatively segmented results from the model with the patients' TCM syndrome types, the potential associations between pathomorphological features and TCM syndrome differentiation have been explored. The analysis revealed no statistically significant differences in the degree of inflammatory infiltration and thrombus formation among different syndrome types, suggesting a complex relationship between local pathological changes and systemic syndrome manifestations.

Objective To evaluate the efficacy and safety of CT-guided percutaneous radiofrequency ablation (RFA) as an alternative for video-assisted thoracoscopic surgery (VATS) in treating multiple pulmonary nodules. Methods A retrospective analysis was conducted on the clinical data of 113 patients with multiple pulmonary nodules admitted to Jiangsu Provincial Hospital of Traditional Chinese Medicine from October 2020 to October 2022. The patients were divided into the RFA group (n=50) and the VATS group (n=63) based on the treatment method. Perioperative indicators (operation time, intraoperative blood loss, postoperative length of hospital stay), oncological outcomes (recurrence-free survival [RFS], overall survival [OS]), and postoperative complication rates were compared between the two groups. Univariate and multivariate Cox regression analysis was performed to identify independent prognostic factors. Results The operation time in the RFA group was significantly shorter than that in the VATS group ([75.2±20.1] min vs [102.3±28.7]) min, P<0.001). No statistically significant differences were observed in intraoperative blood loss and postoperative length of hospital stay. After follow-up of 24 (12, 30) months, no statistically significant differences were found in RFS (HR=1.25, P=0.445) or OS (HR=1.42, P=0.402) between the two groups. Mixed ground-glass nodules with high solid component and solid nodule were identified as independent risk factors for RFS (HR=2.44, P=0.023; HR=2.97, P=0.007) and OS (HR=2.87, P=0.022; HR=3.43, P=0.005) in patients with multiple pulmonary nodules. The total complication rate in the RFA group was lower than that in the VATS group (12.0% vs 34.9%, P=0.009). Conclusions The efficacy of CT-guided RFA in treating multiple pulmonary nodules is comparable to that of VATS, with good safety, and it shows promise as an alternative to surgical treatment for multiple pulmonary nodules.

OBJECTIVE To systematically compare mature experiences of comprehensive drug value assessment in typical countries/regions and to provide decision-making references for China to establish a scientific and standardized comprehensive drug value assessment system for medical-insured drugs. METHODS The literature analysis was used to systematically review drug value assessment frameworks in 11 representative countries/regions, namely the UK, Canada, Italy, Australia, Germany, France, South Korea, Japan, the United States, as well as Taiwan (China) and Hong Kong (China). Comparisons were made across three dimensions: assessment entities, value dimension, and application of results. RESULTS &CONCLUSIONS In most countries/regions, independent technical assessment institutions have been established as part of the drug value evaluation system, with the involvement of multiple stakeholders (e.g., the UK, Canada). The mainstream drug value assessment frameworks have generally transcended the traditional core dimensions of safety, efficacy, and cost-effectiveness, exhibiting two major trends: the continuous expansion of assessment dimensions and stricter evidence requirements. Assessment outcomes are closely integrated with payment policies, ranging from providing technical advice for decision-making (e.g., Italy, France) to directly determining reimbursement eligibility (e.g., the UK, Germany). The following recommendations are proposed for China: first, establish an evaluation mechanism featuring multi-stakeholder participation and separation of evaluation from decision-making. Second, develop a comprehensive evaluation framework integrating clinical, economic, patient, and societal value, emphasizing quantitative indicator exploration and real-world evidence application. Third, promote direct linkage between value-based tiering outcomes and medical insurance reimbursement decisions or access negotiations to balance patient benefits, fund sustainability, and industrial innovation.

ObjectiveTranscranial magneto-acoustic stimulation (TMAS) is an emerging non-invasive neuromodulation technique that may provide a novel non-pharmacological intervention strategy for Parkinson's disease (PD). PD is characterized by the progressive degeneration of dopaminergic neurons in the substantia nigra pars compacta (SNc), leading to motor impairments such as bradykinesia, tremor, and rigidity. Increasing evidence indicates that mitochondrial dysfunction and impaired mitochondrial quality control are central mechanisms underlying dopaminergic neuronal loss. In particular, abnormalities in mitophagy and mitochondrial fission-fusion balance contribute substantially to oxidative stress, energy metabolic failure, and neuronal injury. At present, most clinical treatments for PD mainly alleviate symptoms but do not effectively halt disease progression. Therefore, exploring new interventions targeting the core pathological mechanisms is of considerable significance. This study aims to investigate whether TMAS can improve neural damage and motor dysfunction in PD mice by regulating mitophagy and the fission/fusion dynamic balance, thereby providing theoretical and experimental support for its application in PD treatment. MethodsMale C57BL/6 mice were used in this study. A PD model was established by intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) for 7 consecutive days. After model induction, mice in the intervention group received TMAS once daily for 14 consecutive days, whereas the corresponding control group received sham stimulation. The stimulation target was positioned over the primary motor cortex (M1). Motor performance was evaluated using the pole test and the open-field test. To verify the activation effect of TMAS on the target cortical region, c-Fos immunohistochemistry was performed in the M1. To assess nigral dopaminergic neuronal injury, tyrosine hydroxylase (TH) immunohistochemistry was used to quantify TH-positive neurons in the SNc. Mitochondrial function was evaluated by measuring reactive oxygen species (ROS) levels and adenosine triphosphate (ATP) content in the SNc. Western blot was further performed to determine the expression of mitophagy-related proteins, including PINK1, Parkin, LC3-II, and p62, as well as mitochondrial dynamics-related proteins, including Drp1 and Opa1. ResultsTMAS significantly increased the number of c-Fos-positive cells in M1 (P<0.000 1), indicating effective activation of neurons in the targeted cortical region. Compared with the control group, MPTP-treated mice exhibited marked motor dysfunction, including a significant reduction in total distance traveled in the open-field test (P<0.000 1) and mean speed (P=0.000 1), as well as significant prolongation of turn time and total climbing time in the pole test (P<0.000 1). These behavioral impairments were accompanied by a substantial loss of TH-positive dopaminergic neurons in the SNc, whereas TMAS significantly increased TH-positive neuron survival (P<0.000 1). In parallel, MPTP induced a pronounced increase in ROS levels and a significant reduction in ATP content, indicating severe mitochondrial dysfunction and energy metabolism impairment (P<0.01). TMAS treatment significantly improved motor performance, as reflected by the reversal of MPTP-induced impairment in the open-field and pole tests, and significantly reduced ROS accumulation (P<0.01) while restoring ATP production (P<0.001). At the molecular level, MPTP markedly downregulated PINK1 and Parkin, decreased p62 expression, increased LC3-II accumulation, elevated Drp1 expression, and reduced Opa1 expression, whereas TMAS significantly reversed these abnormalities, suggesting restoration of mitophagy-related mitochondrial quality control and re-establishment of mitochondrial fission-fusion balance. Collectively, these findings indicate that TMAS ameliorates MPTP-induced neurotoxicity and restores mitochondrial homeostasis and energy metabolism. ConclusionTMAS effectively attenuates neural damage and improves motor dysfunction in MPTP-induced PD mice. Its neuroprotective effects are closely associated with multidimensional regulation of the mitochondrial quality control system, including restoration of PINK1/Parkin-mediated mitophagy and rebalancing of Drp1/Opa1-related mitochondrial dynamics. Rather than acting only as a symptomatic neuromodulatory intervention, TMAS may influence a key pathological axis of PD by improving mitochondrial homeostasis in SNc and protecting nigral dopaminergic neurons. These findings provide experimental evidence supporting TMAS as a promising non-invasive physical intervention for PD.

Glaesserella parasuis is the causative agent of Gl?sser's disease in pigs.However,the pathogenic mechanisms underlying its virulence is not yet fully understood.The RuvB protein,a member of the AAA+superfamily,is implicated in various cellular processes,yet its specific role in the virulence of Glaesserella parasuis has not been fully characterized.In this study,we con-structed a RuvB gene deletion mutant,designated ΔRuvB,using the serotype 13 Glaesserella pa-rasuis strain ZJ1208 and a suicide plasmid-mediated natural transformation approach.To elucidate the functional role of the RuvB gene,we comprehensively evaluated the biological characteristics of the ΔRuvB strain through a series of assays,including growth kinetics,colony morphology,bac-terial staining,transmission electron microscopy(TEM),osmotic stress tolerance,high-tempera-ture tolerance,heat shock resistance,UV resistance,capsular polysaccharide quantification,serum bactericidal assays,and murine virulence experiments.Our findings revealed that the growth rate of ΔRuvB showed no significant difference compared to the parental strain.TEM revealed a notable increase in bacterial cell length;however,the number of outer membrane vesicles(OMVs)on the surface of ΔRuvB did not significantly increase.Notably,the ΔRuvB strain displayed a significant reduction in capsular polysaccharide production and serum resistance,as well as diminished toler-ance to UV radiation and high temperatures.Significant alterations were observed in its resistance to osmotic stress or oxidative stress.In the mouse toxicity challenge experiment,in com-parison with the parental strain ZJ1208,the mortality rate dropped by 20 percentage points,suggesting that the virulence of ΔRuvB has been weakened to some extent.Collectively,these results underscore the critical role of the RuvB gene in enhancing the environmental adaptability of Glaesserella parasuis.
10.Protective effect and mechanism of propofol on acute kidney injury in septic rats
Journal of Regional Anatomy and Operative Surgery 2025;34(11):933-937
Objective To explore the protective effect and potential mechanism of propofol on acute kidney injury in septic rats.Methods A total of 84 adult SD rats were randomly divided into the sham surgery group,the model group and the treatment group.The sham surgery group only opened and closed the abdomen,while the model group underwent cecal ligation and perforation for modeling.In the treatment group,propofol(60 mg/kg)was intraperitoneally injected 30 minutes before modeling,and the same dose of propofol was intraperitoneally injected again 6 hours after modeling.The renal function and pathological changes of rats in each group were observed,24-hour survival status of rats in each group were recorded,and the 24-hour survival rate was calculated.A sepsis model was established in vitro by stimulating human renal tubular epithelial cell line with lipopolysaccharide(LPS),and the changes of apoptosis and oxidative stress of renal tubular epithelial cells were observed.The effects of propofol on oxidative stress and apoptosis of renal tubular epithelial cells stimulated by LPS were analyzed.Results The renal function of sepsis rats was decreased,the renal tissue structure was damaged,the 24-hour survival rate of rats was decreased significantly and the survival time was shortened.Propofol could effectively improve renal function,reduce renal Paller score,increase survival rate and prolong survival time in sepsis rats.LPS could induce apoptosis and oxidative stress of renal tubular epithelial cells,while propofol could inhibit oxidative stress and apoptosis of renal tubular epithelial cells.Conclusion Propofol can effectively alleviate acute kidney injury in septic rats,and its mechanism is related to the inhibition of apoptosis and oxidative stress of renal tubular epithelial cells.
